Hi Everybody

I tried to enable SIP Trunking Between two asterisk servers with the following IP Addresses
server1 :192.168.0.141
server2 :192.168.1.141

[color=red]But when i try to call from asterisk server2 extension (001) to asterisk server2 extension (ex 13) and vice verca I recieved the following message “All circuits are busy now,please try ur call …”[/color]
Thanks for ur Helps.

here is the configurations in server1 sip trunk section :

Trunk Name: SipTrunk0to1
PEER Details:
context=from-internal
host=192.168.1.141

;mrh567 is the password of root user of 192.168.1.141 (server2)
type=peer
username=root ;username of server2

User Context: root

Register String: 002:1234@192.168.1.141
; where 002 is an extention on server2 with password 1234

here is the following piece of configurations in server2 sip trunk section :
